The Kraken is a character who appears as an enemy in Disney INFINITY. He appears as a major plot device in the second Pirates of the Caribbean movie. He was later revealed to be dead in the third film.

The Kraken was a legendary sea monster, a leviathan sent to prey on unwary ships and mariners. A fearsome creature with tentacles, closely resembling a giant squid, the Kraken was said to be the length of 10 ships. This terrible beast would be a subject of many legends and lore that circulated for centuries on the Seven Seas.
Few had seen the Kraken and lived to tell the tale. The word "Kraken" was first heard in seagoing lore and mythology, referring to a creature whose many arms or tentacles could reach to the top of a ship's mainmast and could without any great effort capsize a fully-rigged vessel. The huge suckers on the Kraken's tentacles were strong enough to pull the flesh clean away from a sailor's face. Under Davy Jones' command, the Kraken brought Jones ever more souls to join his crew aboard the Flying Dutchman, dying sailors forever impressed into servitude on his cursed ship.

After becoming a marked man with the Black Spot, ensuring that the Kraken would come, Captain Jack Sparrow attempted to find the Dead Man's Chest, which contained the heart of Davy Jones. Jack planned to use the heart to make Jones call off the Kraken. However, Jack's plan ultimately failed as he ended up facing the merciless Kraken as it dragged both Jack and the Black Pearl to the depths of the ocean. Afterwards, to the dismay of Davy Jones, who then served under the East India Trading Company, the Kraken would face death as Lord Cutler Beckett's forces was bearing down on the seas.
